The timezone to use is Bugzilla time — currently PST. In other words, the timestamp, as displayed, of bug 200,000 will decide the winner.

The prize is a limited-edition Mozilla 1.0 commemorative CD, with large red lizard on the front. This is the last one I have, and is bound to increase in value over the years. After all, code ages like wine, right?

If no-one gets it exactly, the prize will go to whoever is closest. The deadline for entries is 12 noon PST on Thursday 14th November — two weeks from today (well, two weeks from last Thursday — Ed).

You are allowed to file bugs at particular times to manipulate the result if and only if you honestly believe they are valid bug reports. :-)
